ABSTRACT:
A Data Storage Pack is disclosed which contains in the same housing (a) a plurality of analog data storage units such as video tape arranged in a two dimensional matrix and (b) a RAM data storage unit. The data in RAM identifies and locates the video data by tape unit in the matrix and location on the tape. The RAM memory units of a plurality of these packs are connected to a central processing unit to permit merger of the digital identification data and thus more efficient use of the RAM space. Pairs of these data storage packs may be stacked spaced from one another. A robot arm and a tape player positioned between the stacks are under control of the RAM data to select and play the desired analog information from the appropriate portion of the appropriate tape in the matrix involved. There are disclosed an advantageous multiple tape cassette arrangement, an advantageous electric motor arrangement for designing and selecting a disk when such is employed as the analog data unit in said matrix, an advantageous robot arm arrangement, and an advantageous data interleaving system for the analog tape.
